An Experimental Method to Investigate the Ageing of Friction Materials is now available from Sylvain Delattre, University of Lille, on the EuroBrake website. He answers a few related questions in this Spotlight.
What do you find most interesting about the topic you are presenting on?
The most interesting thing to me is the new scientific concern about the ageing of friction materials, which seems to change their braking behaviour over a long term, and the methodology that was developped to answer it.
The phenomenon was reproduced experimentally, allowing for the study of its mechanisms, and for the fast development and testing of industrial solutions.
How has coronavirus affected your work and has it had a direct impact on the work you are presenting?
The coronavirus had no impact on the presented work, as it was all done by the time the pandemic got to Europe. The additional work that followed was essentially exploratory, and happened to be slown down without major consequences.
Who do you think will be most interested in seeing your presentation and who would you most like to ask questions about it?
The people most interested in the presented work would be friction material manufacturers and users looking for a relatively simple methodology to test the weathering resistance of their products and to find solutions to improve it.
The people I would like to ask questions about it would be tribologists (on the consequences of weathering on the tribological circuit) and maybe metallurgists studying the ageing of sintered metal parts.
I am a young engineer, passionate about the study of materials and their behaviour. This led me to complete two Masters: one in mechanics of materials and industrial processes, and the other in inorganic chemistry. Now, curiosity led me to study truly complex materials (for friction) under extremely complex sollicitations (tribology and ageing) and to begin a PhD which obviously won't be enough to explore this all.
